Quick Answer
A little, yes. Most electronics draw somewhere between 0.5 and 5 watts while sitting in standby, and across a whole house that habit can quietly add up to 5–10% of your yearly electricity bill. Unplugging everything by hand works, but nobody keeps it up for long. A Standby Saver TV Plug or an energy-monitoring smart plug does the same job automatically, every single time, without you having to remember it.
A few months back, I plugged an energy meter into the socket behind my TV cabinet, mostly out of boredom. Everything in that corner was "off" — TV, soundbar, console. The meter still showed a small but steady number ticking away. Nothing dramatic, just... there, all day, every day, whether anyone was home or not. That's basically the whole story of standby power in one moment, and it's why I keep getting asked whether unplugging things actually does anything.
Short version: it does. Just maybe not in the way most people expect.
What Standby Power Actually Is
You've probably heard it called phantom load, or vampire power, or standby electricity consumption if you want the technical version. It's the electricity a device pulls from the wall even when the screen's dark and the button says "off." That's not a malfunction, by the way — it's on purpose. Your TV needs a trickle of power so it can hear the remote. Your microwave keeps that little clock running because, well, nobody wants a blinking 12:00 forever. Chargers stay half-awake so they're ready the second you plug something back in.
None of that sounds like much on its own. The trouble is scale — you've got this happening in every room, from a dozen or more devices, around the clock, for years. Add it all up and it stops being a rounding error.
Government energy research over the years has put standby power at roughly 5–10% of the average home's yearly electricity use. For a typical household, that can mean somewhere between $100 and $200 spent every year powering… nothing, basically.
So How Much Does Standby Mode Really Cost You?
This is the part people find genuinely surprising because the numbers swing a lot depending on the gadget.
Take TVs. TV standby power consumption on a newer LED or OLED set usually sits around 0.5 to 3 watts, which is small. But older plasma screens, or newer TVs with "quick start" left switched on, can pull 5 to 10 watts constantly — and quick start is the default setting on a lot of models, so you may be paying for a feature you didn't know you turned on.
Microwaves are sneakier still. Microwave standby power might only be 2 to 4 watts for that little digital clock, but here's the catch — a microwave is almost never truly off. You use it for maybe ten minutes a day, tops, and it sits in standby the other 23 hours and 50 minutes. Do the math and the clock ends up costing more over a year than the actual cooking does.
Game consoles left in rest mode for updates can eat anywhere from 10 to 25 watts, which honestly beats what some TVs use while they're actually on. Chargers left plugged in with nothing attached barely register — under a watt each, usually — but most homes have six or seven of them scattered around, and it adds up faster than you'd think.
And then there's the router and cable box. These almost never power down at all. They run close to full power around the clock, which quietly makes them one of the biggest single contributors to standby electricity consumption in most households — bigger than people assume, because nobody thinks of the router as an "appliance."
The real takeaway isn't any one number. It's the pattern: no single device is the villain here. It's twenty small ones, running nonstop, for years, that you never think about.
Does Unplugging Everything Actually Save Money?
Yes. Also — be honest with yourself about whether you'll actually do it.
Pulling one phone charger for a night saves you a fraction of a cent. Not worth the trip. But if you unplugged your entire entertainment setup, your microwave, your printer, and every idle charger in the house, every single day, for a full year? That adds up to something real.
The problem isn't the theory. It's the follow-through. Almost nobody crawls behind the TV stand every night to yank three cables, and even fewer people keep doing it for years without slipping. I certainly don't. That gap between "the fix works" and "people actually do it consistently" is exactly why standby power sticks around as a problem in most homes — and it's exactly the gap that automated smart plugs were built to close.
An Easier Way to Kill Standby Power
Instead of relying on your own memory (which, let's face it, is not the most reliable energy-saving tool), you can let a device handle it for you. This is where the best smart plugs for energy saving actually earn their price.
A few options worth knowing about, depending on what you're trying to fix:
- Automatic standby killers. These sit between the wall and your device, notice when it's gone idle, and cut the power entirely — no app required, nothing to configure. The EcoSavers Standby Saver TV Plug works exactly like this. Plug it in once between the wall and your TV, and from that point on it just quietly handles standby power on its own, restoring the connection the instant you switch the TV back on.
- A smart power strip with energy monitoring. If your TV, soundbar, and console are all clustered in one spot (whose isn't?), a power strip with energy monitoring lets you treat the whole setup as one unit rather than fiddling with each plug separately. Pairing a standby-cutoff device with a multi-socket strip is honestly one of the fastest ways to wipe out phantom load from an entire media corner in one go.
- A manual socket switch for the occasional-use stuff. Not everything needs to be automated. For a coffee maker or a printer you use a couple of times a day, a Socket Switch adapter lets you cut the power completely with one press of a finger, instead of reaching behind furniture for an awkward plug. It's rated for up to 16A/3500W, so it handles most household appliances without issue.
- Timers, for things that don't need to run forever. A screw-in LampBaseTimer E27 adapter or an AC plug timer shuts a light or small appliance off automatically after a set stretch of time — useful for hallway lights, space heaters, or anything you're prone to forgetting about.
Find Out What's Actually Draining Your Power First
Here's the step most people skip, and it's honestly the one that matters most: figure out what's actually wasting power before you buy anything. Guessing is a bit like trying to lose weight without ever getting on a scale.
An energy monitoring smart plug — sometimes just called an energy meter — sits between the wall and whatever you plug into it, then shows you exactly how many watts it's pulling, standby included. The EcoSavers Energy Meter with Large Display does this well, tracking real-time wattage, voltage, cumulative kWh, and even a rough estimate of running cost and CO2 output. Want something smaller and less noticeable? The Energy Meter Mini does the same core job in a more compact shell.
Run it on your TV setup for a week. Try it on the microwave next. Then the router. You'll usually find out fast which devices are actually worth automating and which ones were never really the problem — which saves you from spending money "fixing" something that was fine all along.
Turning This Into an Actual Habit (Not a One-Time Fix)
The households that genuinely lower their bills over time aren't the ones manually unplugging things every night. They're the ones who set up a small system once and then basically forget about it. That's the real idea behind smart home energy management — a handful of automated devices quietly doing the boring, repetitive work so you don't have to remember to.
A reasonable starting point looks something like this:
- A standby-cutoff plug on your TV or entertainment center
- A socket switch on anything you use occasionally, like a printer or coffee machine
- One energy monitoring smart plug you move from room to room to spot the worst offenders
- A timer on lights or heaters in spots people tend to forget, like hallways or garages

A Few Questions People Usually Ask Next
- Is it actually worth unplugging my TV every night? Not really, if we're talking effort versus payoff. Modern TVs draw very little in standby (0.5–3 watts). You'll get more benefit, with a fraction of the effort, by letting an automatic standby saver handle it every single time instead of relying on yourself to remember.
- Which appliances waste the most standby power? Anything that's basically never fully off — your router, cable box, game console, and any microwave with a digital clock. They add up fast simply because they're drawing power around the clock, not because any one of them uses a lot at once.
- Do smart plugs use power themselves, cancelling out the savings? Decent ones are built with very low self-consumption, so the plug itself uses next to nothing compared to what it saves by cutting a device's standby draw. It's a net win, not a wash.
- Is a power strip with energy monitoring better than separate smart plugs? For a cluster of devices in one spot — your entertainment center, say — a monitored power strip is more convenient. For appliances spread across different rooms, individual plugs or a portable energy meter will give you more accurate, device-by-device numbers.
Standby power is real, but it's not something you need to white-knuckle your way through with willpower and a good memory. Find out what's actually wasting electricity with an energy meter, automate the worst offenders with a standby saver or a monitored power strip, and let the rest of it run quietly in the background — the way it should.
